General features of the SAKO language:

• commands similar to sentences used in natural language
• shortening the time required to learn the principles of programming
• ease of use, which reduced coding time
• transparent program code, lowering the probability of making a mistake

It had a static address allocation. It was possible to insert code in SAS macro assembler. The compilation proceeded in two stages:

1. From SAKO to simplified SAS macro assembler (SAS-W).
2. From SAS-W to machine language.

The most characteristic feature of SAKO are Polish commands, e.g. CZYTAJ, SKOCZ DO. It was designed primarily for programming numerical calculations.
